Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

Abstract: Methods and apparatus to support scheduled access control for an electronic lock are described herein. An initiating central wireless device obtains an ephemeral identity resolving key (IRK) to use in resolving an ephemeral resolvable private address (RPA) of a peripheral wireless device. The initiating central wireless device can subsequently connect securely to the peripheral wireless device in order to unlock an electronic lock controlled by the peripheral wireless device to gain access during a scheduled time period. The ephemeral IRK and ephemeral RPA can be used for a limited period of time and/or for a predetermined number of usages during the scheduled time period.

Abstract: An electronic device (such as an access point) that provides a frame is described. This electronic device includes: an antenna node communicatively coupled to an antenna; and an interface circuit, communicatively coupled to the antenna node, that communicates with a second electronic device. During operation, the interface circuit may provide, addressed to the second electronic device, the frame that includes an indication that the electronic device uses a frame-based equipment (FBE) channel access technique and attributes of the FBE channel access technique. The attributes may include: a duration of the FBE channel access technique, and a fixed frame period (FFP) for communication during the FBE channel access technique. Moreover, the frame may be compatible with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.

Abstract: Systems, methods, and mechanisms for an out-of-band (OOB) ultra-wide band (UWB) channel arbitration and/or channel coordination scheme. A device may transmit, periodically, an advertisement packet on an advertisement channel associated with a UWB channel. The device may transmit, according to a UWB channel usage pattern indicated by the advertisement packet, on the UWB channel. The advertisement packet may include a UWB transmit start time offset, a UWB transmit duration, a UWB transmit interval, information to determine a UWB transmit interval, and/or a UWB transmission type.

Abstract: Systems, methods, and mechanisms for an out-of-band (OOB) ultra-wide band (UWB) channel arbitration and/or channel coordination scheme. A device may scan an arbitration channel for a first time period, and based on the scanning, that the arbitration channel is not in use. The device may perform, on the arbitration channel, a first channel access procedure and perform, on the UWB channel, UWB communications during a UWB channel transmission opportunity.

Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Methods, systems and apparatuses for non-access point (non-AP) and access point (AP) multi-link devices (MLDs) are described. A non-AP MLD can transmit, to an AP MLD, a query for information comprising at least one of one or more sets of parameters or identities associated with one or more target AP MLDs. The non-AP MLD can receive, from the AP MLD, a message comprising the information and select, based at least in part on the information, a target AP MLD of the one or more target AP MLDs. The non-AP MLD can transmit a roaming request to the target AP MLD and further receive a roaming response from the target AP MLD.
